The present invention relates to a method for evaluating the performance of an application chain within a computing infrastructure, comprising a number N of resources denoted Ri (1 ≤ i ≤ N), comprising the steps of: collecting, on a same time interval and with the same sampling period periodech of a predefined number M of series of measurements Xk (1 ≤ k ≤ M) relating to the utilization levels of resources Ri; for all possible combinations of two series of measurements (Xk1, Xk2), with k1 ≠ k2: creation of several pairs of subsets (X'k1, X'k2) by selecting a predefined number nv of values from the series Xk1 and Xk2; applying an affine correlation relationship search algorithm (s) on each pair of subsets; calculating percentages P (i) of difference between the values of X'k2 (t) and aX'k1 (t) + b for each index t (between 1 and nv); Calculation of the saturation values of the X'k2 series.
